really low wind... could not take off... the kite is too heavy
If its that light why fly? With different kites of both nature i've seen the same thing equally between the two. Some Lei's fly some foils fly but if its that light its best to stay home.
to one of them had exploded the kite in the first crash 'cause of the cold (-20° / -25°) (it was not a bad crash... just went nose down landing)
Seen the same thing happen with a foil entire rib inside ripped to shreds hopefully the new blowout preventers fix the problem. Plus at -20 kiting isn't the dangerous part the cold is. Again stay home frostbite can cost life and limb.
very long time to set the kite.... and when it's cold it's not nice to not move and eating the cold
Again a compressor makes life sooo easy. you can leave everything attached unwind and go. There is virtually no lag. Also one session of a foil tangle can cost as much time as pumping a big kite by hand. bowtie, collapse, invert all cost time to fix.
need to operate without gloves... in low temperatures your finger will not work after 5min. and also after you set up your gloves, the fingers will not get warm again (when it's cold) (-20 / -30)
You can leave the gloves on to do all the same and if you leave attached lines when folding a lei you don't have to take off your gloves. Again at minus 20 i wouldn't be wearing gloves rather mittens and my session would be cut short by how cold it is.
the kite loose air 'cause the cold... need to re inflate twice or more during the day.
Sounds like a leaky system never had that problem or seen it. unless you leave struts inflated in warm car and move to the cold.
are not the best choice in the super strong wind... not easy to land, not to take off, and if you activate safety system it will be so hard to fix back your lines.
By strong wind do you mean gusty wind foils don't do well in strong gusty winds not much fun to fly in either way. Launch and land are a snap if you have experience with doing so. If you activate the safety on either kite neither is easier then the other they both need to be staked down while you address the problem.
I will never use a foil open cells in the water as much i will never use a pump on the snow.
it's exactly the same thing
You found your preference good for you. Doesn't mean its the only way or what works for someone else.
Other discussion is if you want to "play" to snowkite and in that case you can use also a plastic bag.
But being a short harms (money saver) it's doesn't mean you make the best choice.
Everything has his right use.
There is no such thing as a right or wrong use of kite as there is no such thing as a snowkite. Kites are made differently for different reasons and different people ride different kites as to what they like doesn't make them right or wrong. If it flys you will have fun doesn't matter what you choose they are the same.
